Dysphagia unveiling systemic immunoglobulin light-chain amyloidosis with multiple myeloma.

Dysphagia is an uncommon presentation of systemic immunoglobulin light-chain (AL) amyloidosis with multiple myeloma (MM). Gastrointestinal (GI) involvement usually manifests with altered motility, malabsorption or bleeding. Furthermore, patients identified with GI amyloidosis, without previous diagnosis of a plasma cell disorder, are extremely rare. We report an elderly woman who presented with acute on chronic cardiac dysfunction, sick sinus syndrome and acute renal failure. While admitted, she developed intermittent dysphagia to both solids and liquids. Oesophagogastroduodenoscopy showed ulcerations of oesophagus and duodenum. Biopsies revealed focal amyloid deposition, stained with Congo red. Renal biopsy revealed amyloid deposition in renal arterioles. She underwent a bone marrow biopsy confirming MM, represented by more than 15% plasma cell population. She was started on treatment for heart failure, induction chemotherapy for MM and percutaneous gastrostomy tube for feeding. However, she continued to deteriorate, eventually opting for hospice, and ultimately died 2 days after discharge from hospital.
